作為一種補貼馬達間接變速裝置，伺服電機是指在伺服體系中控制機器元件運轉(zhuǎn)的發(fā)動機，將電壓信號轉(zhuǎn)化為轉(zhuǎn)矩和轉(zhuǎn)速以驅(qū)動控制工具。

As an indirect variable speed device for subsidizing motors, servo motors refer to engines that control the operation of machine components in a servo system, converting voltage signals into torque and speed to drive control tools.

伺服電機重要靠脈沖來定位，伺服電機吸收到1個脈沖，就會旋轉(zhuǎn)1個脈沖對應的角度，從而實現(xiàn)位移。如許，和伺服電機擔當?shù)拿}沖形成了呼應，體系便知道發(fā)了幾多脈沖給伺服電機，同時又收了幾多脈沖返來。因此，也就可以大概很準確的控制電機的轉(zhuǎn)動，從而實現(xiàn)準確的定位。

Servo motors rely heavily on pulses for positioning. When a servo motor absorbs one pulse, it rotates the corresponding angle to achieve displacement. In this way, the pulse generated by the servo motor echoes, and the system knows how many pulses were sent to the servo motor and how many pulses were received back. Therefore, it is possible to accurately control the rotation of the motor and achieve precise positioning.

伺服電機實現(xiàn)了位置，速率和力矩的閉環(huán)控制，高速性能好，穩(wěn)固并電機加減速的動態(tài)相合時間短，利用在火花機，機器手，準確的機器以及單片機控制等。

Servo motors achieve closed-loop control of position, speed, and torque, with good high-speed performance, stable and short dynamic matching time for motor acceleration and deceleration. They are used in spark machines, robotic arms, accurate machines, and microcontroller control.

在利用歷程中必要細致：伺服電機油和水的掩護，伺服電機可以用在會受水或油滴侵襲的場合，但是它不是全防水或防油的。因此，伺服電機不該當安排或利用在水中或油侵的情況中。別的，在移動伺服電機的時，應把隨電機設置裝備部署的那根電纜牢固地牢固到一個靜止的部門，而且應當用一個裝在電纜支座里的附加電纜來延伸它，如許彎曲應力可以減到非常小。

In the process of utilization, it is necessary to be meticulous: the servo motor is protected by oil and water. The servo motor can be used in situations where it is susceptible to water or oil droplets, but it is not fully waterproof or oil proof. Therefore, servo motors should not be arranged or utilized in situations of water or oil invasion. In addition, when moving the servo motor, the cable deployed with the motor should be firmly secured to a stationary department, and an additional cable installed in the cable support should be used to extend it, so that bending stress can be minimized.
